Which of the following describes an organism that oxidizes inorganic substances to obtain energy that is used,in part,to fix CO₂ from the atmosphere? A)photoautotrophs B)photoheterotrophs C)chemoautotrophs D)chemoheterotrophs that perform decomposition

Question

Quizplus · Accepted Answer

Chemoautotrophs are organisms that obtain energy by oxidizing inorganic substances and use that energy, in part, to fix carbon dioxide (CO2) from the atmosphere. This process is also known as chemosynthesis. While photoautotrophs also use CO2 from the atmosphere to fix carbon, they obtain their energy through photosynthesis, not through the oxidation of inorganic substances. Photoheterotrophs obtain both their energy and carbon from organic compounds, and chemoheterotrophs that perform decomposition obtain their energy from organic compounds but their carbon from decomposing organic matter, not from fixing CO2 from the atmosphere.
